They demonstrated that treatment of DNA with sodium bisulfite results in specific deamination of cytosine and conversion into uracil. Deamination of 5-methylcytosine occurred much slower compared to cytosine deamination.

WebThe sulfur in the bisulfite ion acts as a nucleophile and adds to the carbonyl carbon. Because this is such a bulky nucleophile, it will add only to a relatively sterically unhindered carbonyl. This requires the carbonyl to be part of an aldehyde in which one of the R groups is the very small hydrogen, or a ketone having small ‘R’ groups. WebHere, we present a protocol to remove aldehydes and reactive ketones from mixtures by a liquid-liquid extraction protocol directly with saturated sodium bisulfite in a miscible solvent. This combined protocol is rapid and facile to perform. The aldehyde or ketone can be re-isolated by the basification of the aqueous layer.
